Four Ball Machines used for testing extreme pressure, wear Preventive characteristics of lubricating oils, greases & evaluation of cutting fluids and polymer containing oils.

Imperial Four-Ball Machines designed to perform tests as per the following International Standards.


ASTM D2596

Extreme Pressure Properties of Lubricating Fluids and Greases

ASTM D2783

ASTM D2266

Wear Preventive Characteristics of Oils and Greases

ASTM D4172

FTMS 791-6503

IP 239

Extreme-Pressure Properties, Friction and Wear tests for lubricants

GOST 9490-77


The rotating ball is pressed onto three stationary balls of the same size and quality. Wear scars on surface, welding of balls, torque and size of seizure delay is measured with continuously variable speed.


Comprises of :

2 HP variable speed drive Pneumatic loading system
(manual/ programmed) load cells for Friction Force and load measurements Digital display for temperature, speed time, load and friction force


Load Pneumatically activated, continuous loading max range 1000 kg.

Speed Variable speed drive, continuously variable 2HP/220 V Max. range 60-3000 rpm (specify voltage while ordering)

Temperature Thermostatically controlled temperature of specimen holed range ambient to 250°C.

Friction Force High accuracy load cell for measurement of Friction Force between specimens.

Test Time Digital timer for automatic start or shut off.



Comes With:

Basic Machine

Built in Metal Stand

The Control Panel : Microprocessor based Variable Drive AC

Digital Display System: to monitor load, Friction Force, RPM & Temperature

Steel Test Balls, Material EN 31, with Selected Hardness & Tolerance

Test Cups to run Cyclic Fatigue Test and Shear Stability Test

Accessories & Spares to conduct all the above tests

Spare Chucks

Spare Balls (Pack of 2000 Balls)



Micro Processor Controlled System For Data Acquisition & Real Time (on/off) Analysis:

Pentium IV, 1024 MB RAM, 80 GB HDD, CD ROM, 17" Color Monitor, Inkjet Printer PLC, Dedicated user friendly software and Digital Camera (for detailed scar dia. analysis)
